New flood concerns as next atmospheric river makes landfall on B.C. coast
Global News
Multiple weather warnings have been issued for B.C.'s North Coast, and there is concern the system could stress already flood-damaged infrastructure in the south later this week.
Yet another atmospheric river is bearing down on British Columbia, triggering new concerns about rain and possible flooding on both the North and South Coast of the province.
Environment Canada has issued a slew of winter storm, wind and rain warnings, along with special weather statements for Haida Gwaii and the North and Central Coasts as the system brings tropical moisture to the area.
By Sunday afternoon, it said 40 to 50 millimetres of rain had already fallen in the Kitimat area, with another 20 to 30 millimetres in the forecast. The heaviest rain in the north is expected to taper off overnight.
Inland parts of the North Coast, and Stewart, B.C., in particular, were facing a more wintery situation and up to 30 centimetres of snow had already fallen by late Sunday.
Warmer air expected overnight was forecast to deliver heavy rain, possibly mixed with snow overnight.
“The snow will melt as the rain continues and drainage systems could be blocked or overwhelmed,” Environment Canada warned.
“Localized or perhaps widespread flooding could result. Landslides could occur.”
The B.C. River Forecast Centre has maintained a flood watch for the North Coast region.
